Performed the maiden flights on the Skydrill this morning. 7 flights altogether. Flew well on a Cox 6x3 prop but noticeably faster with an APC 4.2x4. Very fast and responsive. Flies on rails like a mini-pattern plane. Fastest .049-powered RC plane I've ever seen(although I haven't seen but a few). Much fun! Here it is with a fresh coat of castor oil slobber. Well earned.

Thanks, Rocketbob. I only wish Time W. was around. Don't know what happened to him. I know his daughter was sick and he was hit by a drunk driver and injured but he came back from all that for a while. It's a shame as he seemed like a great guy and I was looking forward to doing more business with him. I love the Stage 3 Skyline engine he built for me. I'm probably one of the last customers to receive an order from him. His site is still up taking orders and emails but he never responds from what I understand. I wish him well and hope he can return to this hobby/business someday.

I've had good luck with APC props on .049s but you have to adapt the prop hub to fit the engine since the hole is too big. A 6x3 can be made to fit well with a piece of standard fuel tubing but some of the other sizes have a bigger hole and an adapter insert is needed. I've only got one of those and try to be careful not to lose it since I can't seem to find another one to replace it these days.

I'll go with MA then because APCs are heavy and rather than loose a blade, they would cause damage to the shaft, or break the engine loose from the firewall, or worse yet, the firewall from the nose! (happoned to me 1 too many times!).

Every now and then a bundle and engines and props can be found on E-bay, but usually sell for too much in the end.'

Another way to create a perfect fit adapter is to wrap some quality (E.g. 3M) black tape around the prop screw until it's the size of the prop hole. Don't stretch the tape as you wrap. Then use a razor to cut it to the same length as the prop hub. This is simple and it works.
